AIM: To compare culture analysis, Helicobacter pylori (H. pylori) stool antigen (HpSA) test, polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) for H. pylori detection. METHODS: One hundred and thirty-two consecutive adult dyspeptic patients receiving diagnostic endoscopy at the department of gastroenterology were enrolled in this study. Culture and histological examination were performed on biopsy specimens. PCR and FISH tests were applied to histopathological samples. Stool samples that were simultaneously collected were tested for the H. pylori antigen using the HpSA test and bacterial DNA using stool PCR. RESULTS: H. pylori was positively identified by histo-logical examination in 85/132 (64.4%) of the patients, while positive samples were found in 56 (42.4%), 64 (48.5%), 98 (74.2%), 28 (21.2%) and 81 (61.4%) of the patients by culture, HpSA, PCR, stool PCR and FISH methods, respectively. The results of the culture, biopsy PCR, HpSA and FISH tests, with the exception of the stool PCR, were found to correlate with the histological examination as a gold standard. CONCLUSION: The HpSA test is a rapid, simple, and noninvasive test for monitoring therapy. FISH is an accurate, rapid, cost-effective, and easy-to-use test for H. pylori detection. 展开更多

Karst rocky desertification is a geo-ecological problem in Southwest China. The rocky desertification risk zone delineation could be used as a guide for the regional and hierarchical rocky desertification management and prevention. We chose the middle and lower reaches of the Houzhai underground basin on the karst plateau in Puding County, Guizhou Province, China as the study area and selected land use type, elevation, slope, aspect, lithology and settlement buffer as the main driving factors of the rocky desertification. The potential risk of rocky desertification was quantifed with the factor-weights union method and statistical analysis method. Five grades of rocky desertification risk were delineated based on Geographic Information System. The extremely low, low, moderate, high and extremely high rocky desertification risk zones accounted for 5.01%, 44.17%, 33.92%, 15.59% and 1.30%, respectively. As a whole, the rocky desertification risk level was moderate because the area of low and moderate rocky desertification risk zones occupied 78.09% of the study area. However, more than half of the area (about 50.81%) was predicted to have moderate rocky desertification risk and above, indicating that the study area was subject to rocky desertification. Rocky desertification risk was higher in the southeast and lower in the northwest of the study area. Distinct differences in the distribution of rocky desertification risk zones corresponding to different factors have been found. 展开更多

A continuous online in situ attenuated total reflection Fourier-transform infrared(ATR-FTIR)spectroscopic technique was used to investigate the adsorption and desorption kinetics of heptyl xanthate(KHX)on the surface of ZnO and Cu(Ⅱ)activated ZnO.The results showed that Cu(Ⅱ)facilitated the xanthate adsorption process on the surface,and led to the formation of cuprous xanthate(CuX),dixanthogen(X_(2))and xanthate aggregates.The adsorption of xanthate on the surface of ZnO and Cu(Ⅱ)activated ZnO was found to both follow the pseudo-first-order kinetic model.When the NaOH solution was used as a desorption agent,the adsorbed xanthate can largely be removed due to the competition between OH^(−)and HX−.However,for Cu(Ⅱ)activated ZnO,the peak intensities at 1197 and 1082 cm^(−1) had no obvious weakening,and the absorption intensities at 1261 and 1026 cm^(−1) increased in the first 5 min,indicating an ion-exchange reaction between OH^(−)and surface zinc bonded xanthate HX−and the reorganization of adsorbed xanthate. 展开更多

The intrinsic kinetics of iron oxide reduced by carbon monoxide is evaluated by a method of online measuring concentration of off-gas in an isothermal differential micro-packed bed. Under the condition of getting away from the influence of gas diffusion and gas–solid heat transfer and mass transfer, the reaction of Fe2O3 to Fe3O4, Fe3O4 to Fe O and Fe O to Fe in the process of single reaction can be clearly distinguished from each other, and the relevant activation energy is characterized to be 75.4, 74.4, and 84.0 k J·mol-1, respectively. Therefore, the change of surface area in the reaction process due to losing oxygen could be easily calculated by combining it with pre-exponential parameters of Arrhenius equations. In conclusion, these kinetic parameters are verified by the experimental data for the process of ore reduced by carbon monoxide in a packed bed. 展开更多

For efficient energy consumption and control of effluent quality, the cycle duration for a sequencing batch reactor (SBR) needs to be adjusted by real-time control according to the characteristics and loading of waste-water. In this study, an on-line information system for phosphorus removal processes was established. Based on the analysis for four systems with different ecological community structures and two operation modes, anaerobic-aerobic process and anaerobic-anaerobic process, the characteristic patterns of oxidation-reduction potential (ORP) and pH were related to phosphorous dynamics in the anaerobic, anoxic and aerobic phases, for determination of the end of phosphorous removal. In the operation mode of anaerobic-aerobic process, the pH profile in the anaerobic phase was used to estimate the relative amount of phosphorous accumulating organisms (PAOs) and glycogen accumulat-ing organisms (GAOs), which is beneficial to early detection of ecology community shifts. The on-line sensor val-ues of pH and ORP may be used as the parameters to adjust the duration for phosphorous removal and community shifts to cope with influent variations and maintain appropriate operation conditions. 展开更多

The new prototype of the inetto, a helpless and impassive character, makes his first appearance near the end of the nineteenth century in Italian literature, continues to gain strength and status throughout the twentieth-century artistic climate (through the existentialist philosophy of Sartre and Camus) and reemerges in contemporary cinema. The present study examines whether there is a gradual exacerbation or overcoming of this psychological disorder across the centuries in the novels and films investigated. Specifically, I offer a comparative analysis of Svevo's character Emilio Brentani in Senilitd (1898) and Giuseppe Piceioni's Guido in Giulia non esce la sera (Giulia Does Not Date at Night) (2009). This study will also draw unusual parallels between Schopenhauer, Svevo's existentialist philosophy and contemporary cinema. 展开更多

This essay explains why cost accounting, ethical accountability, and accounting principles are interrelated concepts. During the past two decades, the relationship between accounting systems and discharge of accountability has increasingly drawn the attention of researchers. However, researchers have shown a marginal interest in the inclusion and examination of the theme of cost accounting, and in particular, no interest has been oriented to explore the potential role of cost accounting in serving presentation of the trustful cost information as regards the discharge of accountability. In this essay, we will reason that the traditional discourse of cost accounting is fundamentally different from the managerial discourse of cost accounting. The traditional cost accounting is built upon the ethical, legal, professional, and principle-based discourses. By exploring the differences between the two cost accounting discourses, this essay will reduce the effect of current skeptical views with which quality of our academic education, relevance of our research, and our understanding of the potential role of cost accounting in serving the provision and presentation of trustful information have been seriously undermined. 展开更多

The scientific outlook on development, a major strategic line of thought put forward in the report at the CPC Seventeenth National Congress, is a social development strategy based on serious reflection on modern historical development models and views. It exhibits a profound historical consciousness and rational awareness of contemporary human existence in abandoning nihilistic denial of human development, modem developmentalism based on "objective dependence" and the path of alienated development with "objects" as its criterion. This strategy puts people first and promotes man's free and all-round development, with a view to exploring and establishing a new pattern of civilization and realizing a great change in the form of human existence. The far-reaching significance of the scientific outlook on development is to make people clear about how China should develop in modem times and what the path of future development will be. But that is not all, its historical value is yet more deeply embedded in its theoretical exploration of what form of existence human beings should choose. 展开更多

The stress-induced martensitic transformation and its relation with crack nucleation and propagation in CuNiAl shape memory alloy were investigated through in-situ tensile tests by SEM and TEM.The results indicated that the stress concentration ahead of the crack tip could induce formation of stacking faults and different types of martensites.TEM observations showed that the martensites could transform from one type to another and even reversely to the parent during loading.The micro-cracks nucleated along the martensite/parent interface and intersection between two martensites.When the crack propagated a certain distance,the stress concentration ahead of the crack tip was large enough to result in formation of slip bands,and in this condition the microcrack nucleated along slip bands more easily. 展开更多
